2 Claims.

The invention relates in general to a smoking pipe of themulti-chambered stem type and the invention .specifically relates to animprovement in the stem element or stem inserts which define Morespecifically identified, the invention relates to that type of pipe stemwhich is providedadjacent the bowl with a chamber for receiving smokefrom the bowl and incidentally tr'ap therefrom the oily and tarrytobacco condensate juices, hereinafter referred to as the oil trap orcondensing chamber, and from which chamber smoke is drawn into a smokecooling chamber in or adjacent the bit end of the stem and wherein thesmoke is permitted to circulate before being withdrawn and into which isdischarged any saliva or mouth moisture from the smoker.

The primary object of the invention is to provide an improved andsimplified form of pipe of the type outlined which will be maintainedsweet while in use; which can be easily cleaned; and particularly fromwhich the trappedjuices, either those from the tobacco bowl or thosefrom the mouth of the user, may be readily and quickly drained from timeto time as may be necessary.

"The present disclosure particularly features the formingof the stem insectional parts which may be readily separated from eachother and whenseparated provide exposed, easily cleaned surfaces which can be scouredwith the ordinary pipe cleaners.

Smoking pipes as now generally constructed become objectionable largelybecause the briar wood-of which they are usually constructed readilyabsorbs the oily and tarry tobacco condensate and give rise to what iscommonly referred to as.

a strong pipe. It has been suggested heretofore to line the condensingchamber of such pipes with some form of metal liner and which, ofcourse, acts to prevent the contamination of the wood, but as heretoforeconstructed, these metal lined chambers have been designed to permit thesmoke to pass therefrom but have not been provided with any means tofacilitate the cleaning of the same whenever it is desired to dischargethe pipe of its accumulated juices.

Accordingly, another object of the invention is to provide as part ofthe stem insert, a combined funnel and pouring nozzle which will permitand facilitate the emptying of oils from the condenstion of theaccompanying drawing and in part will be more fully set forth in thefollowing particular description of one form of pipe embodying theinvention, and the invention also consists in certain new and novelfeatures of construction and combination of parts hereinafter set forthand claimed.

The accompanying drawing is a view in vertical axial section through atobacco pipe illustratinga preferred embodiment of the invention.

Referring to the drawing, there is disclosed a tobacco bowl Ill providedwith a tobacco chamber I I and an integrally extending neck 12 formingthe inner end of a stem [3, the outer end of which stem is formed bymeans of a bit M. The bit is provided with a plug end l5 forming a tenontelescoping in the open end of the neck l2 to form a two section stem.

The neck is provided with a bore extending therethrough which comprisesan enlarged outer cylindrical portion ll terminating at its inner end ina wall l8 through which extends a relatively constricted portion IQ ofthe neck bore and opening into the bottom of the tobacco chamber.

Referring to the bit l4, it is provided with a bore 2| of relativelysmall diameter projecting inwardly from which is a tube 22 forming anextension of the bore 2! and projecting towards the bowl end beyond aninner wall 23. The inner end of the bit is counterbored to provide asmoke cooling chamber 24 largely contained in the bit and into whichprotrudes axially the inner end of the tube 22. It is understood thatthe structure as thus far described is somewhat conventional and isillustrated herein to show the adaptability of the novel features of thedisclosure to a known form of pipe.

The drawing discloses a metallic construction 25 fitted in the neckboreand comprising a thin walled sleeve 26 wide open at its outer endand provided with a wall 21 at the opposite end. A smalldiametered tube28 extends through the wall 21, projects into and outlines, or at leastpartially outlines.the constricted portion IQ of the bore and leads tothe bottom of the tobacco chamber H. The tube also projects to the rightof the drawing a material distance beyond the wall 21 into the oil trapor condensing chamber 29 outlined by the sleeve 26.

The open end of the sleeve is closed by means of aplug like partition,30 of a readily removable unit 3|, preferably formed of aluminum or:Bake lite. The partition 30 forms the right end of the condensingchamber 29 and the left end closure of the smoke cooling chamber 24. Theunit 3| includes a long tube 32 projecting integrally from the partition30 and. extending therefrom a material distance into the cooling chamberin axial alignment with and spaced slightly from the tube 22 carried bythe bit. This long tube is designed to constitute a pouring nozzle ordrain for discharging the condensing chamber of its oil or other fluidcontent when the bit is removed from the balance of the stem for thispurpose. The tube 32 is of suflicient length to extend a materialdistance into the cooling chamher and thus provide an annular salivadrip receptacle 33, particularly designed for wet smokers. The long tubeprovides a finger piece or handle by means of which the unit as a wholemay be withdrawn from the sleeve and for the purpose of facilitating thefinger engagement the outer end of the tube is provided with a bulbularenlargement 34 to prevent the finger slipping off i the end of the tube.

The side of the partition 30 facing the condensing chamber is providedwith a conical funnellike surface 35 designed to receive drip which mayhug the inner wall of the sleeve 26 and discharge the same through thebore 36 of the pouring nozzle 32. The bore 36 should have a conductingcapacity not only sufficient to convey the smoke therethrough in thenormal operation of the pipe but should also have capacity sufficient topermit the flowing therethrough of the heavy liquid parts of the tobaccocondensate. It is not intended in this structure that the heavy tarswhich settle in the condensing chamber be poured therefrom through thebore 36. These tars are best removed from time to time by withdrawingthe unit from the sleeve and cleaning its inner surface with some ruggedform of cleaning device or pipe cleaner. However, the lighter liquidscan be more frequently discharged from the condensing chamber simply byremoving the bit l4 which thus exposes the pouring nozzle and by merelytipping the shank or stem of the pipe downward the more flowableportions of the condensates may be quickly ejected; the bit restored inplace and thus the pipe is cleaned to this extent and ready for renewedoperation.

The metal parts and preferably the chamber lining shell 26 arepreferably made of an aluminum alloy which functions to quicklydissipate heat from the bowl end of the stem. Oils and tars taken out ofthe smoke in the condensing chamber are prevented from entering thebowland wetting the tobacco; therefore the tobacco may be smoked to thebottom of the bowl with nothing left but ash. However, the constructionis designed so that if the smoker drools saliva while smoking it will betrapped in the chamber 33 at the lower end of the smoke cooling chamberin the event that the smoker habitually smokes with the bowl downward ata lower level than the bit or into the right end of the cooling chamberabout the area into which the tube 22 protrudes in the event that thesmoker habitually smokes with the bowl elevated.

While there have been shown, described and pointed out in the annexedclaims, certain novel features of the invention, it will be understoodthat various omissions, substitutions and changes in the form anddetails of the device illustrated and in its operation may be made bythose skilled in the art without departing from the spirit of theinvention.
